GUSTAVE JEAGER, OF PHILADELPHIA, PENNSYLVANIA.

GEOGRAPHICAL CLOCK.

SPECIFICATION forming part of Letters Patent N 0. 746,517, dated December 03- Application filed October 9, 1902. Serial No. 126,536. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAVE JEAGER, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Clocks or Timepieces, of which the following is a specification.

My invention relates to a new and useful improvement in clocks or timepieces, and has for its object to so construct a clock as to provide for the registration of the hours and minutes upon globes, the hands being made stationary, while the globes are caused to revolve,the actuating mechanism being entirely inclosed in the base which supports the globes.

A further object of my invention is to so adjust the weight of the globes by arranging one directly above the other in a vertical line and supporting them upon pivoted spindles as to reduce the friction incident to the revolving of the globes to a minimum.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand 'how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a front elevation of my improved clock with the glass case removed; Fig. 2, a vertical section through my improved clock.

This invention is intended as an improvement upon a patent granted to me November 28, 1899, No. 637,871, for a globe-clock. In this former patent the clockwork or actuating mechanism was contained within the globes, while in this my present invention the mechanism is contained in the base. Thus the whole apparatus is simplified, and it also simplifies the construction of the globe, as it is not necessary in this invention to have the globes made in halves, and the globes can be made solid, or if made hollow can be made in one piece.

In the drawings, A represents the base, which may be made of any suitable design, and this base is composed of the top and bottom plates A and A respectively. Extending through the lower plate A and in the center of the same is a screw B.

C is a framework arising from the base, and this framework is so formed as to allow the globes D and E to revolve therein. Through the upper end of the framework is threaded a set-screw F, and interposed between the screws F and Bis a vertical shaft G, the lower end having a bearing in the screw B and the upper end having a bearing in the screw F.

The upper globe E is adapted to record the minutes, which are marked around'the equator of said globe, as indicated at E. This globe E is secured rigidly to the spindle G, so as to revolve therewith. The globe D is adapted to record the hours, which are marked in a circle upon its equator, and this globe D is secured to a sleeve, H which surrounds the spindle G and is adapted to revolve thereon. This sleeve H extends downward into the base A and is provided upon its lower end with a gear-wheel H, which meshes with the larger'clock-actuating mechanism I. The spindle G has secured to it within the base A a gear-wheel G, which also meshes with the clock-actuating mechanism I.

Jand J are the indicating-hands, the hand J pointing to the graduations on the globe E and the hand J pointing to the graduations on the globe D. These hands are stationary and are secured to the framework 0.

It will thus be seen that by means of proper gearing the globe E will be caused'to make one complete revolution every hour and the globe D will make one complete revolution every twelve hours, the same as an ordinary clock; but in my invention instead of the hands revolving and indicating the time the globes move and the hands are stationary, and in constructing a clock in this manner the same can be made exceedingly ornamental and unique, and, if desired, the globes may be made of transparent or semitransparent material, so that an-electric light can be contained inside of each globe, so that the time can be quickly read at night.

K is a glass dome or casing adapted to inclose the whole apparatus to preserve the same from damage by dust or contact with surrounding objects.

Of course I am aware that slight modifications could be made inthe mechanism here shown without departing from the spirit of my invention-as, for instance, instead of having the clockworks in the base of the clock said Works might be arranged in the casing above the globes, if desired, and I therefore do not wish to be limited to these exact details, since the gist of the invention rests in the broad idea of arranging a series of globes one above the other and providing suitable mechanism located in the base for the actuation of the globes to indicate the time in connection with stationary hands or pointers.

Having thus fully described myinvention, what I claim as new and useful is- In a device of the character described, a base comprising an upper and lower section GUSTAVE JEAGER.
